Title: Improvements in or relating to apparatus for grading bodies by weight
IPC: B07C5/26
Filed: 1934-03-19
Abstract: 433,387. Grading eggs, fruit, &c. by weighing. REVILL, J., The Retreat, and GRIGG, B. G., Lynden, Kingswood Way, both in Sanderstead, Surrey. March 19, 1934, No. 8577. [Class 143] Relates to a machine for grading eggs, fruit, &c. of the type in which a grading lever having its centre of gravity arranged above its fulcrum receives at one end the egg &c. and at the other end contacts with a cam so that when the lever is moved relatively to the cam it receives an increasing tilt until it overbalances and the egg &c. rolls off. According to the invention the cam comprises alternately sloping and flat portions so arranged that the grading lever will only overbalance at the inclined portions of the cam thereby avoiding discharge of the eggs &c. at points intermediate the grading compartments. The grading levers (one only shown) each comprise arms a, a<1> shaped to receive the egg x and to engage the cam comprising inclined pins h<1> and intervening flat portions h<2>. The grading levers are pivoted on brackets c depending from a turntable continuously rotated in counterclockwise direction by a clockwork or other motor. As the grading lever arrives at the left-hand end of the lowermost horizontal surface h<2> the egg is placed on the lever. A guard plate prevents premature tilting of the lever. On clearing the plate j, the grading lever is free to overbalance as it is carried round and is tilted by the inclined pins h<1>. The pins h<1> extend a little higher than the flat surfaces h<2> so that the grading levers fall back slightly after passing the inclined pins and ensure that no discharge of the egg takes place.

Title: Improvements in or relating to electrically maintained tuning forks or reeds
IPC: H04L13/04
Filed: 1926-03-31
Abstract: 273,398. Muirhead & Co., Ltd., Muirhead, F. H., Neurtley, E. S., and Foll, J. V. March 31, 1926. Electromagnetic interrupters. - A tuning fork or reed A is maintained in oscillation electromagnetically by means of an electromagnet b<1> arranged to exert a pull upon the tines transverse to the direction of oscillation the electromagnet being energized intermittently by a contact a on one of the tines which engages, at the limit of the movement in both direction, with a fixed contact c in the energizing circuit of the electromagnet. Thus the tines are drawn electromagnetically from both their extreme positions towards the normal or central position. In order to obtain fine adjustments of periodicity as is necessary when the forks are used in synchronous telegraphy the position of the electromagnet in relation to the ends of the fork may be varied by means of the screwed spindle E and by supplying the electromagnet through a second winding with a constant excitation which may be adjusted by means of the resistance d. A permanent magnet adjustable along the tines may be used for the same purpose. In modifications an electromagnet with four poles or two electromagnets with two poles each may be arranged to be adjustable together along the tines of the fork.

Title: Improvements in electric resistor construction and method of making the same
IPC: H01C1/084
Filed: 1936-03-26
Abstract: 472,408. Resistances. INTERNATIONAL RESISTANCE CO. March 26, 1936, No. 9062. Convention date, July 2, 1935. [Class 37] In an electric resistance unit comprising a hollow resistor element having separate terminals extending longitudinally thereinto and a good electrical conducting material interposed between the element and the terminals, the resistor element and portions of the terminals adjoining the ends of the element are surrounded by a moulded covering of insulating material liable to be damaged as a result of heat produced by current flow in the resistances, such damage being prevented by cooling the central portion of the element and maintaining a substantially constant temperature throughout its length, this effect being attained by extending the terminal portions inside the hollow resistor element nearly to its central part. The resistance coating 11, which may cover the outer surface of a glass tube 10 or may be arranged spirally thereon, is formed of graphite or finely divided carbon dispersed in varnish and is applied in liquid form to the tube. Terminal members 12, of the shape shown and formed of copper or an alloy of copper and cadmium so as to be good heat conductors, are covered on the parts 15 with liquid conducting material 14 which also comprises finely-divided carbon suspended in a binder, the proportion of carbon being greater than that employed in the coating 11, and the terminal members are then inserted in the tube until the abutments 16 engage the tube ends. As the terminal members move inwards, the material 14 is forced outwards and flows over the ends of the coating 11 and makes a good contact at 19 between the terminals and the resistance coating 11. The resistance is then baked, the parts 19 forming a strong mechanical connection between the terminals and the tube. The unit is then held in a mold and is encased in a block formed of a phenolic condensation product or the like, which surrounds the resistance element and a part of the conical portions of the terminal members. In a modification the terminal members are in the form of wires which are formed with crimps spaced from the ends and taking the place of the abutments 16. Specification 433,047 is referred to.

Title: Improvements in means for automatically controlling the heating of water heaters
IPC: F24H9/20
Filed: 1933-03-28
Abstract: 420,225. Fluid - actuated valves. WOODBRIDGE, W. H., 9, Lloyd Street, Oatley, near Sydney, Australia. March 28, 1933, No. 9305. [Class 135] A device for automatically controlling an electric or gas water heater comprises a chamber 1 into which the supply water enters from the side by a pipe not shown, and two cylinders 2, 3 at the ends of the chamber containing pistons 7, 13 connected by rods 8, 12 to a rocking lever 9, which turns an axle connected to the switch or valve controlling the heating means. The rod 12 may pass loosely through the end of the lever 9 as shown or it may be pivoted to it. The piston 13 is of larger diameter than the piston 7 and is fixed to a hollow stem 19 which slides in a pipe 22 communicating with the water heater. When a tap, not shown, further along the pipe 22 is opened so that water can flow out of the pipe 22 into the heater, the pressure of the water in the chamber 1, acting differentially on the pistons 7, 13, presses down the piston 13 against the action of a spring 23 till the piston enters a wider portion 17 of the cylinder 3 and water can flow through ports 15 in the piston into the portion 17 and thence through ports 20 in the hollow stem 19 into the stem 19 and pipe 22. When the tap is turned off, the reverse action takes place. If, when the tap is turned on, the supply of water fails, the spring 23 returns the piston 13, and the piston 7 and the switch are then moved either by the pivotal connection between the parts 12, 9, or by the weight of the piston 7.

Title: Process for producing glutamic acid
Inventor: OGAWA TETSUO
Filed: 1957-03-21
Abstract: Glutamic acid is produced by extracting beet sugar molasses waste, acidified to a pH of less than 3.0 with mineral acid, with a monohydric aliphatic alcohol containing 4-5 carbon atoms and which is fully or partly (at least 50%) saturated with water, separating the alcoholic phase containing pyroglutamic acid, adding water (which may contain an alkali metal or alkaline earth metal hydroxide dissolved therein), separating the aqueous and alcoholic phases, hydrolysing the aqueous phase to obtain glutamic acid in solution, and crystallizing glutamic acid at pH 3.2.  The hydrolysed aqueous solution may be again extracted with the water-added alcohol before the crystallization.  The extraction of the acidified molasses waste may be effected by a countercurrent multi-stage process.  Fusel oil may be used as the C4-5 aliphatic alcohol.  The process may be applied to Steffen's filtrate, aqua madre, or vinasse.
Patent GB-565389-A (GB)
Title: Improvements in the manufacture of sulphonyl compounds
IPC: C07C311/37
Filed: 1943-06-10
Abstract: Sulphonamides are prepared by treating a formylated aromatic amine with chlorsulphonic acid and converting the sulphonyl chloride so produced preferably by treatment with ammonia into the corresponding sulphonamide of the formylated amine which is then hydrolysed.  The preferred form of the invention relates to the manufacture of sulphanilamide.  The use of the formyl compound is stated to have the advantage that the hydrolysis step results in the formation of formic acid in a condition suitable for re-use.  In an example, formanilide is treated with chlorsulphonic acid and the sulphonyl chloride so produced reacted with ammonia. The crude sulphonamide so produced is hydrolysed wish caustic soda and the sulphanilamide precipitated from the alkaline solution with hydrochloric acid.  The filtrate from the sulphanilamide is concentrated and then heated with aniline hydrochloride to give a good recovery of formanilide which may be re-used.  The Provisional Specification describes the employment in place of the formylated aromatic amine of any formylated aromatic base. This subject-matter is not contained in the Specification as accepted.

Filed: 1927-04-05
Abstract: 282,258. Woodall-Duckham (1920). Ltd., Wellington, S. N., and Scott, A. April 5, 1927. Density separators.-Dust is extracted from a current of air, and graded, by passing the current through a cyclone separator to separate the coarser particles and then through one or more baffle chambers in which the finer particles are deposited. A collecting cone b forms the lower end of the cyclone casing a and an axial exit pipe c extends from this cone through the upper cover into the vessel e provided with conical baffle plate f. A pipe g from the top .of the vessel e is connected to a suction fan. A helical blade d surrounds the pipe c, there being a slight clearance between the blade and the casing. The dust laden gas is collected from the chamber o and passed through the pipe h, its collection and passage being assisted, if desired, by the injection of steam or air through the inlet p. The stream from the pipe h enters the casing a tangentially and passes down the helical blade while the coarse particles are separated. The stream then passes up the pipe c to the separator e where the finer particles are deposited. Vertical pipes k are connected to an annular blast pipe i surrounding the cyclone a and carry nozzles l which direct air or steam on to the blade d to cause the dust to collect in the cone b. A similar nazzle m in the separator e directs a blast to carry the collected dust through the opening n in the pipe c. Additional separators similar to the separator e may be superposed on the apparatus.

Title: Improvements in or relating to vehicle seats
IPC: B61D33/00
Filed: 1953-04-07
Abstract: 762,660. Reversible seats. LAMBERT, W. March 8, 1954 [April 7, 1953], No. 9369/53. Class 52 (2). Relates to reversible seats in which the back 15, when swung over, moves the seat part 1 in the opposite general direction and alters the inclination of the seat part. The seat 1 (Fig. 1), pivots on shafts 3 mounted on two upright supports 5 each provided with two oppositely-inclined upper faces 7 upon which the seat bears. The back 15 is pivoted at each side to two links 17 fixed to two shafts 19, 21. When the back is swung over, upper shaft 19 rotates and a cam 23 thereon moves a loop-like follower 25 pivoted at 27 from the position shown to the corresponding position cn the opposite side. During this motion, a projection 29 on the follower drives the seat 1 in the opposite direction to the movement of the back by engagement in a recess 31 on the seat. Rotation of cam 23 also causes one of two arms 33 pivoted thereto to retract one pivoted seat stay 35 and the other arm 33 to project the other seat stay 35 to seatsupporting position. Shaft 21 slides in a vertical slot 47 at each end and shafts 19, 21 carry cog wheels 37 connected by a chain 45. The chain is tensioned by jockey cog wheels 37 and shaft 21 is biased to the lower position by a spring 43. In a modification, Fig. 3, shaft 19 carries an arm 49 which, when the back is swung, rotates anticlockwise as shown to clear the left-hand seat stay 35 which is retracted by spring 53 and then to raise the right-hand stay 35 which engages a push-block 51 both to move the seat bodily to the right and to tilt the seat 1 up the other way. The seat 1 and the back 15 are cushioned by rubber stops 11.

Abstract: 1,197,865. Fuel injection control systems. ROBERT BOSCH G.m.b.H. Feb. 21, 1969 [Feb. 23, 1968], No.9403/69. Addition to 1, 154, 270. Heading G1N. In an I.C. engine fuel injection control system as disclosed in the parent Specification, the duration of the pulse T 1  from the monostable multivibrator 32 is further controlled in dependence upon the temperature of an engine part e.g. the oil in which an N.T.C. resistor 121 is mounted. As described the N.T.C. resistor 121 is operative below 0‹ C., the pulse becoming larger the greater the engine oil temperature is below 0‹ C. The N.T.C. resistor 96 is arranged to sense the temperature of a different engine part to that of resistor 121 e.g. the cooling water system, exhaust system or cylinder head, and the time constant of R121 is preferably five times greater than that of R96. R96 then determines 60% to 80% of the required temperature correction of the injection period and R121 determines 40% to 20% of the correction.

Title: Shifting register utilizing magnetic amplifiers
Inventor: KAUFMANN HENRY WILLIAM
IPC: G11C19/04
Filed: 1957-03-22
Abstract: 832,925. Magnetic amplifiers. SPERRY RAND CORPORATION. March 22, 1957, No. 9451/57. Class 40 (9). [Also in Group XIX] A shifting register comprises "magnetic amplifier " (i.e. saturable core) stages each including a feedback loop, normally closed transfer gates between the stages, and control means for selectively breaking the feedback loops and opening the gates. The shifting registers described employ a " non-complementing magnetic amplifier," i.e. a device which gives an output signal only when an input signal is supplied thereto. The " amplifier " shown in Fig. 2 comprises a core 20 of material having a substantially rectangular hysteresis loop. The core may be of various shapes, e.g. cup-shaped or toroidal, and may be of ferrite or comprise strips of magnetic tape. In the normal or resting state, the positive and negative " power pulses," Fig. 3A, applied from point 23 to output winding 21, are used up in driving the core alternately to its positive and negative remanent condition and no appreciable output is obtained. If, however, a positive input pulse, Fig. 3B, is applied to input coil 22 this will counteract the effect of the negative power pulse with which it coincides so that the core remains in the positive remanent condition. Thus the next positive power pulse will be presented with a relatively low impedance, thus producing a positive pulse output, Fig. 3C, at 24. Each stage of the shifting register shown in Fig. 8 comprises a pair of non-complementing amplifiers ANC, such as 80, 81, which are controlled by " phase 1 " and " phase 2 " power pulses #1P, #2P respectively, Fig. 9, A and B. Any pulse applied to stage I via serial input buffer 89 or parallel input buffers 90, 91 will be recirculated through gate G1 which is normally opened by pulses from a " complementing " magnetic amplifier AC (Fig. 6, not shown), the subsequent stages II &c. being similar. The recirculation pulses from AC are stopped by applying either a clear pulse to input 95 or a shift pulse to input 98, the latter also operating non-complementing amplifier 100 to cause transfer gates G2, G4, &c. to be opened to transfer the outputs of " phase 2 " amplifiers 81, 85, &c. to the next higher stages. In a circuit diagram (Fig. 10, not shown) the gates and buffers comprise diodes. One of the amplifiers in a stage may be replaced by passive delay means. In another shift register (Fig. 4, not shown) in which successive stages operate in opposite phase, each stage comprises one non-complementing magnetic amplifier and delay means which may comprise a lumped constant delay line. It is stated that this register can be used as a ring counter.
